(B) * 310
(C) 324
(D) 280​

Answer 1

Answer:

Rs. 324 is the correct answer

Explanation :

When we listen percent we recognized that it means 100.

We will multiply 360 to 100 and then divide it by 10. This we can easily do by cross multiplication.

Price. Discount

100 10

360 ?

We have to do cross multiplication

360×10 = 3600/100 = 36 rupees

We have to subtract 36 from 360 rupees

360-36 = 324 is the correct answer
